What is it?A portable, powered speaker system designed for small to medium wavefront applications. DetailsThe KR400S features a line array of 24 x 3” high efficiency neodymium drivers housed in a durable, “ultra-strong chassis” suitable for demanding operating conditions. The system also incorporates KL21ma sub-woofers with 21” Neodymium drive units engineered for maximum linear excursion. The ultra-light reflex cabinet is fitted with four pocket handles and one 35mm pole mount for easy installation of the satellite speakers. The onboard Class-D amplification is capable of delivering 1800W power output to both the sub and satelite enclosures, producing a maximum SPL of 132dB across a frequency range quoted at 30Hz – 19kHz (+/-3dB). With its line array design and built-in DSP system, the KR400S is said to deliver “outstanding power and coherence” throughout its coverage area together with a wide dynamic range and faithful sound reproduction. The onboard DSP offers 16 dedicated presets, dynamic limiting, plus over-current, over-temperature and short-circuit protection and is remote controllable via PC control software.
